To me, it seems like the only benefit of an SSD cache is that it persists across reboots. That's nice for a workstation, but it seems useless for a server.

RAM cache is certainly higher performance than SSD.
Remember that DSS doesn't provide any RAM cache for BLOCK IO LUNs/shares, only FILE IO, so in that case the SSD cache provided by MaxIQ would be extremely beneficial.
